LUBRICATOR.

Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed April 22, 1907. Serial No. 369,450.

To all whom it may concern:

Be it known that we, WILLIAM W. KEEFER and CHARLES E. WARD, residents of Pittsburg and Banksville, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to the lubrication of car axles and other rotating shafts or journals, and it is designed with special reference to the requirements of mine cars having axles which rotate in bearings secured to the car. I

It is a common practice to locate an oil box or reservoir beneath a journal and to convey the lubricant up wardly ther-pto, usually by a ring depending from the journal into the oil. The oil is held within the receptacle so long as the latter remains upright, but when the car is tilted, and in fact turned, completely upside down, as is often the case when emptying its contents, the journal is flooded and much of the oil wasted.

The primary object of this invention is to so construct the oil receptacle as to confine the oil regardless of the position in which the car and the oil receptacle may be placed.

The invention is an improvement in the oil receptacle shown in Letters Patent granted us .Tune 5, l906, No. 822,671, relating to mine cars, and while designed primarily for use in this connection, it is obviously not restricted thereto.

In the accompanying drawings, Figure 1 is a side elevation of a mine car, partly in section, showing our improvement applied thereto, and Fig. 2 is a similar end view. Fig. 3 is a vertical sectional view of one of the bearings and the oil receptacle, taken on line 3 3 of Fig. 4. Fig. 4 is a sectional view taken on line 4 4 of Fig. 5, and Fig. 5 is a similar view, inverted, taken on line 5-5 of Fig. 4.

Referring to the drawings, 2 designates the body of the car, and 3 the bearings secured to the under side thereof in which axles 4 are adapted to rotate.

5 are the wheels. As shown in our above mentioned patent, the bearings on each side of the car are preferably formed integral with a sill member G extending longitudinally of the car; this, however, being only incidental to the present improvement.

Each of the bearings consists of an integral box-like structure, and formed longitudinally therethrough is the circular axle or journal passage 7, which constitutes the immediate bearing, while the lower portion 8 of the structure forms the oil-confining receptacle. Bearing 7 is divided by the ring slot or passage 9 formed downwardly therethrough and open at the top for the insertion and removal of the lubricating ring 10, which hangs loosely therein upon the journal and depends into the oil chamber. Coincident with the ring slot 9 are the two parallel walls or partitions II, reaching nearly to the bottom of the oil chamber, thus dividing the latter into two compartments I2 and 12/ which freely communicate beneath partitions 1l, where they are also open to the ring space 9, thus affording the oil free circulation in the chamber and around the depending part of the ring. The oil may be inserted through an oil passage 13 extending inwardly through the axle or journal and branched at its inner end at 13 to intersect ring slot 9. With the oil chamber thus constructed, the car may be tilted either on its side, or its end, or it may be turned completely upside down without wasting the oil, the latter being held within either compartment l2 or 1.2/ or in both, when the car and bearing are in any of the abnormal positions mentioned.

vWe claim l. A journal bearing having a depending oil chamber Wholly closed excepting for a vertical ring passage open through the bearing surfacey and means for preventing oil from escaping from the chamber through said passage when Athe bearing is inverted.

2, A journal bearing having a depending oil chamber closed excepting l'or a ring passage open through the bearing surface, thechamber having a compartment beneath said passage which is open only at its lower end to the remainder of the chamber.

A journal bearing having a depending oil chamber closed at the top or beneath the bearing surface excepting for a ring passage, and walls at opposite sides of the passage, said walls extending downward from the top of the chamber and reaching to opposite sides thereof with the spaces at opposite sides of the walls communicating only WILLIAM lV. KEEFER. CHARLES E. WARD.
